In my opinion, for 'most cases':

** You will be offered a base salary equal or equivalent to what you could have earned in your own country of origin **

The difference is supposed to be a tax advantage if you can sort out your fiscal status with your own country.

A person from one continent, will not be offered salary based on the standard of living of another continent.

The bottom line is: your 'Gross Income' will be about the same as in your country of origin.

The reasoning is simple: if Qatari companies could find all their labour needs within Asian countries, then they wouldn't initiate hiring campaigns in the West.

If western Expats were offered 'Asian' level salaries, then they would just stay home.
